If i is a normal variable: then it is -30i^2 - i*j + 20j^2
If i is the constant i, then it is 20j^2 -i*j + 30
Answer:
x=11
Step-by-step explanation:
Vertical angles are congruent, so m∠A = m∠B.
4x+8 = 5x-3
Subtract 5x from both sides.
-1x+8=-3
Subtract 8 from both sides to isolate the variable.
-1x=-11
Divide both sides by -1 to solve for x.
x=11
Plug in 11 for x into m∠A=(4x+8)=(4(11)+8)=(44+8)=52.
Given:
Mean, μ = 196
Std. dev., σ = 22
A sample size of 50 (> 30) is large enough to provide meaningful data.
The random variable is x = 200.
The z-score is
z = (x - μ)/σ = (200 - 196)/22 = 0.1818
From normal distribution tables, obtain
Prob(X < 200) = 0.572 = 57.2%
Answer: 57.2%
